Low temperature water gas shift (LTS)

The low temperature shift catalysts from Topsoe are well-proven technology which, based on many industrial references, are known for their high activity, stability and resistance to poisons. Through intensive research and development LTS catalysts with drastically reduced methanol by-product formation have successfully been introduced on the market. Presently R&D focuses on the development of new versions of LTS-catalysts characterised by even higher S-capacities ensuring prolonged lifetime of the industrially operated catalysts. 

Medium temperature water gas shift (MTS)

In hydrogen plants a single medium temperature shift reactor is frequently the preferred solution for optimisation of the hydrogen yield. Based on in-house research and development Topsoe has developed the MTS catalysts LK-817 and LK-813 - which ensure optimal performance in terms of stable activity, high selectivity and high mechanical strength.

High temperature water gas shift (HTS)

For the high temperature water gas shift reaction, typically performed at 320-450ºC, a Cu/Fe-oxide/Cr-oxide based catalyst (SK-201-2) is used. In the near future, an increasing amount of synthesis gas production will be based on coal gasification instead of natural gas. HTS feed gases produced by coal gasification typically contain more CO and less water compared to the conventional feed gas. The focus of the current research in HTS is to handle feeds produced by coal gasification, while preserving the stability and quality of the HTS process.
